Both roles suit those seeking flexible schedules in tech industries.

What are some unique challenges and benefits of working as a weekend software engineer?

As a Weekend Software Engineer, you may face challenges such as collaborating with team members who primarily work weekdays, which can require proactive communication and clear documentation. However, this role also offers flexibility and the opportunity to focus on tasks with fewer real-time interruptions. You’ll likely work on maintenance, urgent bug fixes, or project sprints scheduled for off-peak hours. This experience can enhance your problem-solving skills and may position you for future roles that require adaptability or involve critical support work. Additionally, many organizations value weekend engineers for their reliability and willingness to support essential systems outside standard hours.

What are the key skills and qualifications needed to thrive as a weekend software engineer, and why are they important?

To thrive as a Weekend Software Engineer, you need strong programming skills, problem-solving abilities, and a relevant degree or coding experience. Familiarity with popular development tools, version control systems like Git, and cloud platforms is typically required. Effective time management, self-motivation, and clear remote communication are critical soft skills for this role. These skills ensure you can deliver high-quality code efficiently while collaborating with teams or clients during limited weekend hours.

What is a weekend software engineer?

Job description

Worker Sub-Type:

Regular

Job Description:

QNX enhances the human experience and amplifies technology-driven industries, providing a trusted foundation for software-defined businesses to thrive. The business leads the way in delivering safe and secure operating systems, hypervisors, middleware, solutions, and development tools, along with support and services delivered by trusted embedded software experts. With a focus on reducing hardware dependency and increasing efficiency, QNX empowers organizations to unlock new possibilities in areas like high-performance computing at the edge, standards-based virtualization technologies, and cloud enablement. QNX technology has been deployed in the world's most critical embedded systems, including more than 275 million vehicles on the road today. QNX software is trusted across industries including automotive, medical devices, industrial controls, robotics, commercial vehicles, rail, and aerospace and defense.

Are you the person we are looking for?

At QNX, we are building the next generation of middleware that powers virtualization and real-time performance across a wide range of platforms.

As a Systems Software Developer on our Middleware team, you will design, implement, and maintain VirtIO virtual devices - including virtual sockets, shared input, shared filesystems, and shared messaging systems.

In this role, you will also play a key part in the functional safety lifecycle, ensuring software complies with rigorous industry standards like ISO 26262 (ASIL D). Additionally, you will directly support our customers,

delivering specialized engineering services, integration support, and custom solutions to help launch their mission-critical products into production.

If you're an early-career systems engineer who thrives on lowlevel systems work, has a strong foundation in C/C++ and realtime concepts, and is passionate about pushing the limits of embedded middleware, this is the role for you.

You will

  • Develop VirtIO virtual devices that expose virtualized hardware to guest operating systems, ensuring lowlatency and highthroughput communication.
  • Collaborate with hardware vendors and Android AOSP teams to codesign device drivers, memory mappings, and interrupt handling for virtual devices.
  • Partner directly with customers and field engineering teams to provide specialized integration support, troubleshoot deployment blockers, and deliver tailored middleware solutions.
  • Optimize realtime performance across the stack, from kernelspace drivers to userspace libraries and conduct rigorous profiling and tuning.
  • Stay ahead of industry trends in virtualization and embedded security, and contribute directly to product roadmap and design discussions.

You will have:

  • Strong foundational knowledge of software development, with a proven proficiency in C/C++ programming and real-time systems concepts gained through relevant internships, academic coursework, or complex personal projects.
  • Familiarity or exposure to QNX RTOS (kernel, device drivers, IPC, memory management).
  • Understanding of or exposure to virtualization concepts (VirtIO, hypervisors) or Android AOSP framework layers is a strong plus.
  • Basic understanding of hypervisors such as QEMU and Xen is desirable.
  • Foundational exposure to lowlevel programming (DMA, interrupts, memory mapping, device driver architecture).
  • Excellent communication skills and the ability to work collaboratively across hardware, OS, and application teams.
  • A passion for experimentation - you love prototyping, testing new ideas, and turning them into productiongrade code.
  • Bachelor's (or higher) degree in Computer Science, Software Engineering, or Computer Engineering.

If you are looking to make a real impact, then we'd love to hear from you!
